The Trial of a Time Lord, titlecard [Doctor Who Collectors’ Wiki*]

Season 23 of Doctor Who starred Colin Baker as the Sixth Doctor, Nicola Bryant as Peri Brown and Bonnie Langford as Melanie Bush. Though produced as four separate serials from a practical standpoint, it aired as a single, connected serial entitled The Trial of a Time Lord.

Appearing throughout Season 23 were Michael Jayston as the Valeyard who acted as the prosecutor in the Doctor’s trial, with Lynda Bellingham as the Inquisitor, presiding.

The Ultimate Foe

The Ultimate Foe was the unbroadcast title given to episodes 13 and 14, the concluding episodes of The Trial of a Time Lord. This story marked the final appearances of Colin Baker as the Sixth Doctor, of the Inquisitor and the Valeyard as recurring characters, and a final appearance of Nicola Bryant as Peri Brown in a cameo to give her character closure under happier circumstances than what the events of Mindwarp had offered. This was also the last of the Master’s annual appearances on the show; he wouldn’t appear again until Survival in Season 26.

First broadcast November 29 – December 6, 1986
